Dual Head Screw

Abstract

This present invention relates to a dual head screw that features at least one male nut driver extending outwardly from a base head opposite the shaft of the screw. The dual head screw replaces standard female head screws, thus eliminating concern over stripping of the screw head or the same becoming compacted with debris. The dual head screw has a shaft with a threaded section, a base head and the male nut driver. The male nut driver is dimensioned in size to withstand the torsional forces associated with installing or extracting the dual head screw from an object, and may be driven or extracted with a standard hand tool or a power drill. In a further embodiment, the male nut driver may be comprised of a first driving portion and a second driving portion.

What is claimed is: 
     
         1 . A dual head screw comprising:
 a shaft;   a base head; and   a male nut driver.   
     
     
         2 . The dual head screw of  claim 1 , wherein the base head comprises a first surface and a second surface, and further wherein the second surface is opposing to the first surface. 
     
     
         3 . The dual head screw of  claim 2 , wherein shaft extends outwardly from the first surface and the male nut driver extends outwardly from the second surface. 
     
     
         4 . The dual head screw of  claim 2 , wherein the base head has a diameter that is larger than a diameter of the shaft. 
     
     
         5 . The dual head screw of  claim 3 , wherein the male nut driver is smaller than the diameter of the base head but larger than the diameter of the shaft. 
     
     
         6 . The dual head screw of  claim 5 , wherein the shaft comprises a threaded portion. 
     
     
         7 . The dual head screw of  claim 6 , wherein the shaft comprises a penetrating tip. 
     
     
         8 . The dual head screw of  claim 7 , wherein shaft has a taper such that the diameter of the shaft is smaller near the penetrating tip than the diameter of the shaft near the base head. 
     
     
         9 . The dual head screw of  claim 8 , wherein the male nut driver has a substantially square cross-section. 
     
     
         10 . The dual head screw of  claim 8 , wherein the male nut driver has a substantially circular cross-section. 
     
     
         11 . A dual head screw comprising:
 a shaft;   a base head; and   a male nut driver, wherein the male nut driver has a first cross-section and a second cross-section.   
     
     
         12 . The dual head screw of  claim 11 , wherein the base head comprises a first surface and a second surface, and further wherein the second surface is opposing to the first surface. 
     
     
         13 . The dual head screw of  claim 12 , wherein shaft extends outwardly from the first surface and the male nut driver extends outwardly from the second surface. 
     
     
         14 . The dual head screw of  claim 13 , wherein the base head has a diameter that is larger than a diameter of the shaft, and further wherein the male nut driver is smaller than the diameter of the base head but larger than the diameter of the shaft. 
     
     
         15 . The dual head screw of  claim 14 , wherein the shaft comprises a threaded portion and a penetrating tip. 
     
     
         16 . The dual head screw of  claim 15 , wherein shaft has a taper such that the diameter of the shaft is smaller near the penetrating tip than the diameter of the shaft near the base head. 
     
     
         17 . The dual head screw of  claim 16 , wherein the male nut driver further comprises a groove. 
     
     
         18 . The dual head screw of  claim 17 , wherein the groove is positioned between the first cross-section and the second cross-section. 
     
     
         19 . The dual head screw of  claim 17 , wherein the groove is positioned along either the first cross-section or the second cross-section. 
     
     
         20 . A dual head screw comprising:
 a base head;   a tapered shaft extending outwardly from a first surface of the base head, wherein a diameter of the tapered shaft becomes smaller the farther away from the base head;   a plurality of threads positioned along at least a portion of an exterior surface of the tapered shaft; and   a male nut driver, wherein the male nut driver has a first cross-section and a second cross-section, and further wherein the first cross-section is different than the second cross-section.
